Emerging Therapies for Prostate Cancer Are Targeting the Effects of Androgens

Androgens are male sex hormones. These hormones are also known to stimulate the growth of prostate cancer cells in the body.

However, new classes of drugs and therapies are now targeting these hormones so as to control and stop the growth cancerous cells originating from the prostate. The British Journal of Urology International describes these new treatments.

These facts were contained in a recent review made on its current edition. The following is an online extract providing details on these emerging treatments for prostate cancer. You are going to find it quite revealing and interesting:

 Androgens are sometimes called the “male hormones.”  They contribute to a man’s sexual functions and are associated with secondary characteristics like chest and facial hair.

The most common androgen is testosterone. Getting this hormone under control may help control prostate cancer.

Prostate cancer needs androgens – including testosterone – to develop, grow and multiply. New classes of drugs targeting these hormones could be an effective, low-side-effect treatment alternatives for prostate cancer.

A recent review in the British Journal of Urology International describes the emerging drug therapies.

“What we realized is that production of androgens like testosterone depends on an intact system in which the brain recognizes hormone levels, signals the pituitary to increase or decrease production, and the pituitary in turn sets the testes in motion,” said E. David Crawford, MD, investigator at the University of Colorado Cancer Center and a co-author of the review.

He continued, “Additionally, by targeting the production of androgens by the testes, we could break that system at many other points.”

The review looks at the history of pharmacological approaches, including estrogen and luteinizing hormone releasing hormones or LHRHs, that interrupted the flow of communication and thus disrupted the process. These drugs had serious side effects, though.

Another class that currently shows potential are LHRH antagonists, such as enzalutamide (formerly known as MDV3100). These drugs immediately drop testosterone levels. Prostate cancer cells go after these androgen antagonists first, and then can’t get to the testosterone.

Also new on the scene are drugs called androgen biosynthesis that block androgen production from all sources, including the testes, adrenals and the cancer itself.

The first of this class to gain U.S. Food and Drug Administration (FDA) approval in April 2011 was Zytiga (abiraterone).

In an email to dailyRx, Dr. Crawford summarizes these developments, “Testosterone is the key regulator of the prostate cancer cell. All of these new agents work to block the production or action of testosterone. This is an exciting time in the therapy of prostate cancer management.”

“As these new drugs make their way from the lab to clinic, we expect the ability to offer androgen antagonists to patients whose cancers have resisted other treatments,” U.S. Food and Drug Administration.

Dr. Crawford has a financial relationship with enzalutamide manufacturers Medivation Inc. and Astellas Pharma Inc., which are currently seeking priority FDA review of the drug.

The above information is quite revealing. It is good to know that more and more therapies for prostate cancer are targeting the male sex hormone that has been discovered to be responsible for cancer growth. Each of the emerging therapy tackles prostate cancer cells in its own way and has worked more for patients with advanced prostate cancer.

More so, it should be noted that many first line treatments for the advanced stage of this has been to target the effects androgen as a stimulator for cancer of the prostate.

It is also good to know that most of these therapies have received approvals from the US Food and Drug Administration (FDA).
